Unfiltered MU in 3.0 and Security Concerns

Anyone have any suggestions on a best practice for allowing users to embed videos? Is Unfiltered MU still frowned upon for security reasons in 3.0? Is Viper's video quicktags still a preferred way? Would love to remove Viper's to get rid of yet one more plugin, but concerned about security issues with Unfiltered MU. Is the WPMUDEV tags plugin safer at all? Any feedback appreciated!
